That's the first choice of _AC_PROG_CXX_EXIT_DECLARATION; it sets
ac_declaration to the empty string, and then tries to compile a program
like this:

  $ac_declaration
  @%:@include <stdlib.h>

which expands to


  #include <stdlib.h>

which is what you're asking for.

It could be either, but you need to investigate more what's going on.
You might try runing "configure" with "sh -x configure".
